Baby sleep sound
Heartbeat sound for babies
A soft, steady pulse like the heartbeat a baby heard for nine months. Simple, gentle, and often the first sound parents reach for.
About this sound
The heartbeat was part of a baby's world before birth, so the rhythm is familiar. The app's heartbeat is a slow, muffled thump, not a sharp medical beat. It repeats evenly and loops without a gap, so there is no sudden change to wake a light sleeper.
Why parents use it
Rhythm gives the brain something predictable to follow, and a calm rhythm is easy to relax into. Parents often pair it with holding, rocking or patting, because they all share the same slow pace. It also adds a little sound to a quiet room without the hiss of white noise.
Good for
- Newborns who like a slow, familiar rhythm
- Babies who find hissing sounds too sharp
- Cuddle time and the wind-down before bed
- A softer sound for naps
Using it safely
- Keep it quiet. Heartbeat sounds carry well even at low volume.
- Try matching the pace to a calm, slow rhythm when you rock or pat, then let the sound carry on while you step back.
- Do not use a plush toy that plays a heartbeat inside the crib. Keep the sound source out of the sleep space.
- If your baby is not settling, try a steady sound such as white noise or brown noise.
Frequently asked questions
Does a heartbeat sound really calm babies?
Many babies relax with it, and it feels familiar to many parents too. Evidence for any single sound is limited, so treat it as something worth trying rather than a guarantee.
Can I play it all night?
You can, at a low volume and from a distance. The app also has a sleep timer. See white noise all night.
